Semiconductor device and lateral diffused metal-oxide-semiconductor transistor

Abstract

The invention provides a semiconductor device and a lateral diffused metal-oxide-semiconductor transistor. The semiconductor device includes a substrate having a first conductive type. A gate is disposed on the substrate. A source doped region is formed in the substrate, neighboring with a first side of the gate, wherein the source doped region has a second conductive type different from the first conductive type. A drain doped region is formed in the substrate, neighboring with a second side opposite to the first side of the gate. The drain doped region is constructed by a plurality of first doped regions with the first conductive type and a plurality of second doped regions with the second conductive type, wherein the first doped regions and the second doped regions are alternatively arranged.
